At 10:13 p.m. Wednesday, the U.S. Coast Guard notified police that a commercial dive boat and its operator had been reported missing. Another tour company picked up the boat’s customers from a dive spot off the Kailua-Kona coast.

The inflatable boat Sea Wolf and its operator were later found drifting offshore and were towed to Honokohau Harbor by another boat. Shortly after midnight Thursday, police arrested the operator of Sea Wolf, 30-year-old Spencer Erwin of Kailua-Kona, on suspicion of operating a vehicle under the influence of an intoxicant.
